Patent ES-357109-A1 (ES)
Title: Thermistor controlled refrigeration expansion valve
IPC: G05D23/275
Filed: 1968-08-09
Abstract: A refrigeration system comprises an expansion valve 16 operable to control refrigerant flow from a condenser 12 to an evaporator 14, a valve actuator 36, 40 responsive to an electrical signal to control the flow in dependence on the temperature of a thermistor 50 exposed to respond to either or both the temperature and physical state of the refrigerant. Valve actuator comprises a bi-metal plate carried on the end of needle valve 26, heated by a winding 36 and urged by spring 40 into contact with a metal ring 46. Thermistor 50 is suspended by its leads 52, 60 to contact the refrigerant and the leads 52, 60 pass into a thermally and electrically insulating terminal assembly 56. Thermistor 50 is connected in series with batteries 66, a manual or bi-metallic switch 68 which also controls the compressor 10, a variable resistor 86 to set the overall flow of refrigerant, and heater winding 36. A switch 88 shunting resistor 86 permits operation at a higher level. A high value resistance 82 in parallel with thermistor 82 increases its sensitivity. Thermistor 50 has a negative temperature co-efficient so that current through it rapidly increases on closing switch 68 thereby causing bi-metal winding 36 to heat bi-metal plate 38 and open the normally closed expansion valve 16. When excess refrigerant is passed through the evaporator 14 the thermistor 50 responds immediately to the change to liquid state, its resistance increases and the valve 16 tends to reclose. A normally open switch 84 controlled by a temperature sensitive element 85 exposed to evaporator 14 shunts thermistor 50 whenever there is the danger of evaporator freeze up. In Fig. 2 (not shown) two thermistors are strapped to the inlet and outlet ends of the evaporator so that their self heating effects are reduced. Increase in outlet temperature of the evaporator is detected by the outlet thermistor which causes valve 16 to open. Increase in inlet temperature is sensed by the inlet thermistor which causes an increase current flow in a circuit in parallel with the valve actuator thereby tending to close valve 16. The inlet and outlet thermistor therefore tend to maintain the temperature differential across the evaporator constant. A switch permits just the inlet thermistor to control valve 16 to maintain the evaporator temperatures and pressures constant.
Patent ES-361528-A1 (ES)
Title: Apparatus and process for liquefying and revaporizing gases
IPC: F17C9/04
Filed: 1968-12-17
Abstract: Liquefied gas, e.g. natural hydrocarbon gas, having been transported in a reservoir from a production point to a consumption point, is vaporized by direct heat exchange with a cold carrier which is substantially insoluble in the L.N.G. and is of greater density, e.g. a 70: 30 water-ammonia mixture, the so-cooled carrier is then fed to the reservoir, transported to the production point and used to liquefy natural gas by direct heat exchange therewith. In operation cooling to effect liquefaction of feed natural gas occurs in three direct contact heat exchangers 12, 13, 14, Fig. 3, in series. Feed gas entering at 18 flows upwardly past trays 15 in exchanger 12 in counterflow to melted cold carrier introduced at 16 and discharged at 17, condensed impurities being withdrawn at20. The so-cooled gas enters exchanger 13 through an injection nozzle 21 and draws a mixture of granular solid and liquid carrier admitted at 24 up a capped riser 22 resulting in formation of a layer of liquid gas which is withdrawn at 23 and liquefaction of the solid carrier which is withdrawn at 26. The liquefied gas is further cooled by feeding at 30 into the bottom of an exchanger 14 and passage upwardly against downward flowing granular carrier admitted at 29 and agitated by a rotor 27. The so-cooled liquefied gas is separated from carrier at 31 and discharged at 33. Liquefied gas to be re-vaporized is admitted at 40, Fig. 4, and flows upwardly through an exchanger 34 against downward flowing powdered carrier admitted at 39 and agitated by a rotor 37. Warmed liquefied gas leaves exchanger 34 at 43 and ascends an exchanger 35 to which carrier in the liquid phase is fed at 45 and is withdrawn in the solid phase at 47. Vapour from exchanger 45 is then warmed in exchanger 36 against downward flowing carrier liquid and is withdrawn as product gas at 52.

Title: Apparatus for the preparation of copies during both directions of relative movement of an original
IPC: G03G15/04
Filed: 1974-10-28
Abstract: A document copying machine is disclosed, of the type in which the original moves reciprocally relative to an illumination slot so as to be exposed line-by-line from one end to the other, a receptor element, which may be a copy sheet taken from a supply stack, a selenium drum or other receptor surface, moving in one direction and having an image of the original transmitted to it by image beam guide devices located between the illumination slot and the receptor element. The machine has double the productive capacity of conventional copying machines where there is relative movement of the original and the exposure or illumination slot, in that a copy-producing image is transmitted, on relative movement of the original and the slot in one direction, on to a receptor element and a second copy-producing image is transmitted, on opposite relative movement of the original and the slot, on to a second receptor element or on to the same receptor element moved to a further position. The images of the original are transmitted by way of reflector or prism systems cooperating with at least one objective lens in such a way that an image of the original is transmitted true-to-line by one system as relative movement of the original and the slot takes place in one direction and a second image of the original is transmitted, again true-to-line by reason of line and side reversal, as relative movement of the original and the slot takes place in the other direction, the second reflector or prism system moving into place or otherwise becoming operative, instead of the first reflector or prism system, as the original and the slot reach the end of their relative movement in the first direction.
